Projeto e modelo de um conversor boost interleaved

Abstract

The aim of this paper is to analyze and design a boost power converter utilizing the interleaved technique, which improves the load transient response, provides better heat dissipation and less stress on the semiconductors. To represent the interleaved boost converter in a mathematical model, its state space representation is used, where the parasitic resistance of the inductors and semiconductors is considered. In this context, the interleaved boost converter is controlled using a cascade structure with the input current on the inductors in the inner loop and the dc-link voltage in the outer loop. After investigating the response of the controllers in the frequency domain, indicating the stability of the system, the converter is validated by simulations and by experimental measurements highlighting the correct operation of the system, reaching the desired voltage with small residual ripple amplitude.
